Title: Method and apparatus for communication via an extended virtual personal area network
Inventor: XUN FEI
IPC: H04W4/80
Filed: 2015-12-22
Abstract: A communication system is provided wherein multiple communication devices of a user may collaborate with each other via an extended virtual Personal Area Network (EVPAN). When the user exits his car and leaves one of his collaborative devices in the car, and travels out of Personal Area Network (PAN) range of the device in the car, the communication system provides for the user to take advantage of the collaborative features the device left behind in the car by bridging the PAN with a WAN via an EVPAN server. Further, the communication system provides for collaborative communication devices to communicate with each other without a need for users of such collaborative communication devices to be authenticated. For example, someone picking up a first communication device of a user can connect to a second, collaborative communication device of the user without the person using the first communication device being authenticated.

Title: Methods, systems and apparatus for controlling movement of transporting devices
Inventor: ROB STADIE
IPC: G06Q10/08
Filed: 2015-06-03
Abstract: The system and method disclose determine and reserving routes for moving transporting devices, moving transporting devices when transporting one or more of a plurality of containers, and control the transporting devices to retrieve one or more of the plurality of containers from within one or more of a plurality of stacks. Prior to retrieving the desired container from within the stack, other (undesired or non-targeted) containers require moving. The undesired containers are moved by placing each of these undesired containers in an optimised position chosen from a pool of empty location, excluding the original stack from which it was removed. This allows for the position of the undesired container to be optimised based on the layout of the grid-like structure. The grid structure may comprise locations of workstations or charging stations. The placement optimisation may also be based on the frequency at which a type of item is requested, future ordering predictions, or congestion levels. The movement and actions of the transportation devices can also be optimised to limit the number of movements the devices have to take. These sorts of system are used with in warehouses and storage facilities.
